A new electrophilic selenocyanation reagent N-selenocyanato-dibenzenesulfonimide was readily prepared in two steps from commercially available dibenzenesulfonimide for the first time. A variety of electrophilic selenocyanato reactions of nucleophiles have been achieved using it as selenocyanato source under mild and simple conditions. Numerous SeCN-containing compounds were obtained in moderate to

The interception of σ-alkyl-palladium complexes in catalysis is a powerful strategy for the generation of molecular complexity. We have demonstrated a palladium-catalysed carboborylation reaction for the synthesis of borylated indanes, which proceeds in good yields and moderate enantioselectivity.

A new method for the construction of 2-substituted and 2,2-disubstituted chromans via Pd-catalyzed carboetherification reactions between aryl/alkenyl halides and 2-(but-3-en-1-yl)phenols is described. These reactions effect formation of a C-Obond and a C-Cbond to afford the chroman products in good yield, and also provide stereoselective access to tricyclic chroman derivatives.
